To the untrained eye, blade irons all appear to be quite similar, small flat-backed golf clubs absent of a cavity—but to a trained eye and hand, a quick glance or simple pass of a finger over a surface or edge will reveal more information than a small book could ever hold.

Now when it comes to two men that could write books about how a blade iron should look and feel, Jack Nicklaus and Katsuhiro Miura are names on a very short list and their years of experience that have been brought together to create a single set of irons years in the making—these are the Nicklaus X Miura collaboration blades.

We were teased this collaboration in early June (Miura Golf teases Nicklaus collaboration) and now the details have arrived.

The Specs

Although they look similar to another blade in the Miura line, the MB•101, this is an entirely new iron that has been meticulously crafted to match the specs of Mr. Nicklaus with a reconfigured flatter sole profile with additional bounce and adjusted offset through the set. Jack was never known for taking divots and his preference has also been to see the leading edge sit closer to the ground with a straight leading edge—these irons deliver on the preference.

The specs are very similar to the MacGregor sets Jack used throughout his career crafted by legendary club maker Don White while he was with MacGregor, the difference now is that instead of being forged in the United States, these new irons will be forged and ground by the skills craftsman at Miura golf in Himeji, Japan.

The last detail beyond the sole comes down to looks, and these new irons have been subtly ground where the hosel meets the leading edge of the iron to create Nicklaus’ preferred look from address—creating an almost underslung leading-edge, something that was popular with both original MacGregor Nicklaus irons and before that original Hogan blades.

As mentioned in the original teaser, a collaboration between Nicklaus and Miura would almost seem inevitable since both brands are held under the 8AM Golf umbrella, which also has Golf Magazine and True Spec golf, among others, but the origin of this project dates back many years before Miura was held by 8am and was actually set in motion in 2014 when Jack himself made a visit to meet the legendary club maker Mr. Miura in Japan and to tour the Miura factory.

“The day Jack visited the factory was the best day of my life,” Miura-san.
